Hybrid tea rose plant named ‘Wingold’

ABSTRACT

A hybrid tea rose plant variety producing yellow flowers.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid tea rose variety which was originated by my crossing as seed parent the variety known as ‘Gold Medal,’ U.S. Plant Pat. No. 5,177, and an undistributed, unnamed, unpatented seedling as pollen parent. The varietal denomination of this new rose is ‘Wingold’.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by the new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive yellow flowers.

Asexual reproduction by budding of the new variety as performed outdoors in Kern County. Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. Other known forms of asexual reproduction may be also used.

COMPARISON WITH PARENT

New variety differs from its undistributed pollen parent in flower color and size.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
